[iam-TJ]

Here's a clause from a U.K. (England and Wales) lease agreement that is pretty standard:

35. Landlord's Covenant for Quiet Enjoyment

The Landlord covenants with the Tenant, that, so long as the Tenant pays the rents reserved by and complies with the obligations of this lease, the Tenant shall have quiet enjoyment of the Property without any interruption by the Landlord or any person claiming under the Landlord except as otherwise permitted by this lease.

There are clauses covering emergency entry for repairs (e.g. burst water pipes, leaking gas) in short-term rental agreements but - as others have said - they require "reasonable" notice in almost all cases aside from dire emergency, and the tenant can still refuse entry.
